TPS3306-15DR datasheet by Texas Instruments

TPS3306-15DR Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the TPS3306-15DR?
  The maximum input voltage that can be applied to the TPS3306-15DR is 18V, but it's recommended to keep it below 15V for optimal performance and reliability.
• How do I ensure the TPS3306-15DR is stable and doesn't oscillate?
  To ensure stability, make sure to follow the recommended PCB layout guidelines, use a low-ESR output capacitor, and add a 10nF-100nF ceramic capacitor between the VIN and GND pins.
• What is the minimum input capacitance required for the TPS3306-15DR?
  The minimum input capacitance required is 1uF, but it's recommended to use a 4.7uF-10uF ceramic capacitor to ensure stable operation.
• Can I use the TPS3306-15DR in a high-temperature environment?
  The TPS3306-15DR is rated for operation up to 125°C, but it's recommended to derate the output current and input voltage at higher temperatures to ensure reliability.
• How do I calculate the output voltage of the TPS3306-15DR?
  The output voltage of the TPS3306-15DR is fixed at 15V, but you can adjust it by using an external resistor divider network or a voltage feedback pin.
